afneter nose; The invention further `relates to that type f clamp whereinthere is a Single metal band,apor'tion ofv'vhich i"s reduced in Width tb `passthrough a sl'ot yin another `portion 'of the band to permit Wrappihg'of the band about the fhse and maintaininga substantially continuous `contact Ief the bandereundthe hose, l

A primary objectfof the invention is `t`o maintain divided portions ofthe band in side by s'ide VYfixed relation byA an exceedingly simple and effec` i tive tie permitting relative "longitudinal or cirv eumfere'ntiai shifting between the'vband` parts. s other important' objects anu advantages of the intention `Will bc'orne apparent to those -ver'sed in the' 'jart iin tlielfollwrig description of `one Fig. 3,a` view'in perspective of the clamp structure with the clamping `holtremained `and the elempin an exeandedstate; s s s s in seetiondon the une at in v Fig. 4, a detail Figa; and l -i rtg. 5, a detail mseeuonenthe `line sus in` Fig. 2:

Like characters of reference indicate like parts throughout the several Views in the drawing.;

the band l'o iying on each side ef ,thefsiema spe'ctive ends of thefslfot I3. i

This terminal end I is preferably ofthe same `Width 'as that ofthe band liandis formed in 1 the samefrnaner as the other terminal'end `II by having the end-`vvra`tp` 'around acylinder `I5 and be carried around back on its 'outer face to be welded theret'of` A boltII isv revolublynpassed transversely through a"hole` I8 in the cylinder I2 (the terminal end IIlbieingut awayaround the cylinder to permit insertion ofthe bolt II the"re through) and the bolt is screw-threaddlyengaged through the cylinder I6 (the terminal lend The width ef the tngeinnig, 2; will normally' approximate twice the `Winther 'that tornen er Therefore when the clamp is used `for larg'ez-di-` A band, generallydesignatd by the `numeral I0; is" formed to havea terminal end II carrying any suitable boltengaging device, herein Ashown asa cylinder I2` around which the end II is 1 wrapped to extendover and against the outer face of the end portion II and be secured thereto `Icy any suitable means, such as by welding. Starte` ing from` this terminal end II and vpreferably 1spaced from thewelding zonejust indicated is a slot I3. Then `the band IIJ continues in its full width from the end of that slot I3 aroundinside of the terminal end II. l

A tongue I4 continues integrally from this por#l tion of the band `I0 and is formed `to have a width Vthat will permit it to pass through the slot I3 with the inner and outer `faces of the arn'eterliose,` and theiclamp is` madeout'of light gauge i metal, there {"wouldr be p a tendency,` fplartieularly in shipping andhandling for tliefparts` f the banden each side of the' slot I3 to'becoine v s spread apart orpushed in, in overlapping relation, from4 or over. thetongue I4,resulting in olif-V` iiculty and time consuming operations-entire part' of the Workman in attempting to install the 4 clamp on the hose in production Work.; Oneparticular presentd use of the` clamp' andstructure forming the present `invention is on a hose'having approximately; a t rivel inch diameter. f It is` to be s. understood, of coursethat the Aclamp is adaptable for use on hose havigawiderange dfdiameters.

To prevent displacement ofthe clainp band portions, as above indicated, a tie I9 is carried @across the slot I3 to interengage the parts of the band I0 on each sideof that slot. Inthe present form, this tie I9 is in integral part of the band I0.

This tie I9 is `carriedacross betweenthose parts of the band I0 to have its inner faceiin a plane j suiciently spaced outwardly from the plane of the inner faces of those band parts so as to per.-

\ `mit the tongue `I4 topass across inside of thetie "I9 and by the tie I9 the tongue I4 in theplane of the `facesof those band parts.

Then in order to prevent inward displacement l `oi? the tongue I4 relative to those band parts on tongue I 4 maintained `in parallel alignment with i thefaees of that part of the band I0 extending laterally from each side of the slot I3. This tongue I4 is inserted through` the slot I3 `from the inside of the band and is carried on out and around to have a terminal` end I5 overlapping the outside of the band` I 0 to extendover that each side ofthe slot I3, a strap 20 is secured attached to the tongue each edgeofthe tie I9.

which lies,` between. the re` maintain the innerf'ace of tie I 9 to slide freely therebetween. Furthermore, the ends of the strap 20 are spaced apart a. sufficient distance to permit circumferential travel of the tongue I4 relative to the tie I9 which is required in drawing the strap ends II would dig into and distort the hose being clamped.

Furthermore, the external side of the clamp is also left without any protruding members that would engage the operators hands or clothing during and after the clamping action.

While I have herein-shown and described my invention in the one particular form, it is obvious that structural'variations may be employed without departing fromthe spirit of the invention and I therefore do not desire to be limited to that precise form 4beyond the limitations as may be imposed by the following claims.

1. A hose clamp comprising a band having a longitudinal slot through a length thereof; a reduced width portion of the band beyond saidslot forming a tongue; .said band and tongue being rolled and lapped upon itself to have the tongue carried from the inside to the outside of the band through said slot; a terminal clamp end on .each end of said band; means for pulling said ends one toward the other to set up` circumiern ential, relative travel between said tongue and the balance of said band; and a tie across said slot interconnecting the band portions on each side thereof, said tie being offset from said por- 4tions to pass across the outer side of saidl tongue to position the inner side of the tongue in substantially the same plane as that of the inner sides of saidv portions.

2. A hose clamp comprising a band havinga longitudinal slot through a length thereof; a reduced width portion of the band beyond said slot forming a tongue; said band and tongue being rolled and lapped upon itself to havethe tongue carried from the inside to the outside of the band through said slot; a terminal clamp end on each end of said band; meansfor pulling said ends one toward the other to set up circumferential, relative travel between said tongue and the balance of said band; and a tie across said slot interconnecting the band portions on eachside thereof, said tie vbeing offset from said portions to pass across the outer side of said tongue to position the innerv side of the tongue in substantially the same plane as that of the inner sides of said portions; and a strap secured by its ends tothe outer said of said tongue to extend slidingly over said tie, said strap ends being norvmally spaced from said tie.

' y 3. A hose clamp comprising a band having a longitudinal slot through a length thereof; a reduced width portion of the band'beyond said slot forming a tongue; said band and tongue being rolled and lapped upon itself to have thetongue carried from the inside to the outside of the band through said slot;l a terminal clamp end on each endof said band; means for pulling said ends one ltoward the other to set up circumferential, relative travel between said tongue and the balance of said band; and a tie across said slot interconnecting `the band portions on each side` thereof, said tie being offset from said portions to pass across the outer side of said tongue to position the inner' side of the tongue in substantially the same plane as that of the inner sides of said portions; and a strap secured by its ends to the outer side of said tongue to extend lsliclingly over said tie, said strapends being nor.-

mally spaced from said tie; said tie being located at substantallythe longitudinal center of said slot, and said band portions each being ap'` proximately. half the width of said tongue.

4. In a hose clamp, the combinationlwith a band having a longitudinal slot through a length thereof; a reduced width portion of the band beyond said slot forming a tongue; said band and tongue being rolled and lapped upon itselfto have the tongue carried through from the inside-to the outside of the band through said slot; and band end engaging means to set up circumferential travel of the overlapping band parts; of a tie across said slot spacing Vthe band portionson each side thereof a distance substantially equal to the width of said tongue; and means interen gaging said tongue and said tie to permit circumferential travel therebetween but to limit radial travel of the tongue from the tie; said tie being externally of said tongue.
